AUSFÜHRLICHE BESCHREIBUNGDETAILED DESCRIPTION
Ausführungsformen der vorliegenden Offenbarung sind hierin beschrieben. Es versteht sich, dass gleiche Bezugszeichen, die in unterschiedlichen Zeichnungsansichten vorkommen, identische oder funktionell ähnliche Strukturelemente bezeichnen. Ebenso versteht sich, dass die offenbarten Ausführungsformen lediglich Beispiele sind und andere Ausführungsformen verschiedene und alternative Formen annehmen könnten. Die Figuren sind nicht unbedingt maßstabsgetreu; einige Merkmale könnten übertrieben oder minimiert sein, um Details bestimmter Komponenten zu zeigen. Daher sind bestimmte strukturelle und funktionelle Details, die hierin offenbart sind, nicht als einschränkend zu interpretieren, sondern lediglich als repräsentative Grundlage, um den Fachmann zu lehren, die Ausführungsformen auf verschiedene Weise anzuwenden. Wie der Fachmann verstehen wird, können verschiedene Merkmale, die unter Bezugnahme auf eine der Figuren dargestellt und beschrieben sind, mit Merkmalen kombiniert werden, die in einer oder mehreren anderen Figuren dargestellt sind, um Ausführungsformen zu erzeugen, die nicht ausdrücklich dargestellt oder beschrieben sind. Die Kombinationen dargestellter Merkmale stellen repräsentative Ausführungsformen für typische Anwendungen bereit. Verschiedene Kombinationen und Modifikationen der Merkmale, die mit der Lehre dieser Offenbarung übereinstimmen, könnten jedoch für bestimmte Anwendungen oder Realisierungsformen erwünscht sein.Embodiments of the present disclosure are described herein. It goes without saying that the same reference symbols which appear in different drawing views denote identical or functionally similar structural elements. It should also be understood that the disclosed embodiments are merely examples, and other embodiments could take various and alternative forms. The figures are not necessarily to scale; some features could be exaggerated or minimized to show details of certain components. Therefore, certain structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching those skilled in the art to practice the embodiments in various ways. As will be understood by those skilled in the art, various features shown and described with reference to one of the figures can be combined with features shown in one or more other figures to produce embodiments that are not expressly shown or described. The combinations of features shown provide representative embodiments for typical applications. Various combinations and modifications of the features consistent with the teachings of this disclosure, however, may be desired for particular applications or implementations.
Die hierin verwendete Terminologie dient der Beschreibung bestimmter Aspekte und soll den Umfang der vorliegenden Offenbarung nicht einschränken. Sofern nicht anders definiert ist, ist sämtlichen hierin verwendeten technischen und wissenschaftlichen Begriffen die gleiche Bedeutung eigen, die ihnen der Fachmann dem Gebiet zuschreibt, zu dem diese Offenbarung gehört. Obwohl alle Verfahren, Vorrichtungen oder Materialien, die den vorliegend beschriebenen ähnlich oder gleichwertig sind, bei der Anwendung oder dem Testen der Offenbarung verwendet werden können, werden nun die folgenden beispielhaften Verfahren, Vorrichtungen und Materialien beschrieben.The terminology used herein is used to describe certain aspects and is not intended to limit the scope of the present disclosure. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as attributed to them by those skilled in the art to which this disclosure belongs. Although any methods, devices, or materials similar or equivalent to those described herein can be used in the practice or testing of the disclosure, the following exemplary methods, devices, and materials are now described.

Obwohl oben beispielhafte Ausführungsformen beschrieben sind, ist nicht beabsichtigt, dass diese Ausführungsformen alle möglichen Formen beschreiben, die durch die Ansprüche umfasst sind. Bei den in der Beschreibung verwendeten Wörtern handelt es sich um beschreibende und nicht um einschränkende Wörter, und es versteht sich, dass verschiedene Änderungen vorgenommen werden können, ohne vom Grundgedanken und Schutzumfang der Offenbarung abzuweichen. Wie zuvor beschrieben, können die Merkmale verschiedener Ausführungsformen kombiniert werden, um weitere Ausführungsformen der Offenbarung zu bilden, die möglicherweise nicht ausdrücklich beschrieben oder dargestellt sind. Zwar hätten verschiedene Ausführungsformen in Bezug auf eine oder mehrere erwünschte Eigenschaften als vorteilhaft oder bevorzugt gegenüber anderen Ausführungsformen oder Implementierungen nach dem Stand der Technik beschrieben werden können, der Fachmann erkennt jedoch, dass für ein oder mehrere Merkmale oder Eigenschaften ein Kompromiss eingegangen werden kann, um gewünschte Gesamtsystemattribute zu erreichen, die von der konkreten Anwendung und Realisierungsform abhängen. Diese Attribute können unter anderem, ohne auf diese beschränkt zu sein, Kosten, Festigkeit, Haltbarkeit, Lebenszykluskosten, Marktfähigkeit, Aussehen, Verpackung, Größe, Gebrauchstauglichkeit, Gewicht, Herstellbarkeit, Montagefreundlichkeit usw. umfassen. Sofern Ausführungsformen in Bezug auf eine oder mehrere Eigenschaften als weniger wünschenswert als andere Ausführungsformen oder Realisierungsformen nach dem Stand der Technik beschrieben werden, liegen diese Ausführungsformen daher nicht außerhalb des Schutzumfangs der Offenbarung und können für bestimmte Anwendungen wünschenswert sein.While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms encompassed by the claims. The words used in the description are meant to be descriptive and not restrictive, and it is understood that various changes can be made without departing from the spirit and scope of the disclosure. As previously described, the features of various embodiments can be combined to form further embodiments of the disclosure that may not be expressly described or illustrated. Different would have Embodiments with respect to one or more desired properties can be described as advantageous or preferred over other embodiments or implementations according to the prior art, but those skilled in the art will recognize that a compromise can be made for one or more features or properties in order to achieve desired overall system attributes that depend on the specific application and form of implementation. These attributes can include, but are not limited to, cost, strength, durability, life cycle cost, marketability, appearance, packaging, size, usability, weight, manufacturability, ease of assembly, and so on. To the extent that embodiments are described as less desirable than other embodiments or implementations according to the prior art with respect to one or more properties, these embodiments are therefore not outside the scope of the disclosure and may be desirable for certain applications.
